The Central Intelligence Agency on Wednesday released 470,000 additional files found in May 2011 when U.S. Navy SEALs killed Bin Laden in Pakistan.

According to experts at the Foundation for Defense of Democracies who were allowed to see the files before they were released, the material revealed more details about ties between the Sunni extremist group and Shiite Iran.

The files show there was some sort of an agreement that if Al-Qaida attacked American targets in the Middle East, it could receive arms and money from Iran and training in Hezbollah military bases.

Last month, CIA Director Mike Pompeo had promised to release documents about Iran and Al-Qaida relations for the public to see.

On Thursday, Zarif dismissed the documents by calling them “fake news” in a tweet, adding that the U.S. “can’t whitewash role of US allies in 9/11”, in an apparent reference to Saudi Arabia.

In the years since the 9/11 attacks, media reports have surfaced alleging that members of Osama Bin-Laden’s Family visited or lived in Iran and some members of the extremist group were allowed to travel through Iran.
